The MAX8512’s output voltage can be adjusted with an external divider.The MAX8510/MAX8511 are preset to a variety of voltag-es in the 1.5V to 4.5V range.

The MAX8510 requires only 1μF (typ) of output capacitance for stability with any load. When disabled, current consumption drops to below 1μA.Package options include a 5-pin SC70 and a tiny 2mm x 2mm x 0.8mm TDFN package.Applications●Cellular and Cordless Phones ●PDA and Palmtop Computers ●Base Stations●Bluetooth Portable Radios and Accessories ●Wireless LANs ●Digital Cameras ●Personal Stereos●Portable and Battery-Powered EquipmentFeatures●Space-Saving SC70 and TDFN (2mm x 2mm) Packages ●11μV RMS Output Noise at 100Hz to 100kHzBandwidth (MAX8510)●78dB PSRR at 1kHz (MAX8510) ●120mV Dropout at 120mA Load●Stable with 1μF Ceramic Capacitor for Any Load ●Guaranteed 120mA Output●Only Need Input and Output Capacitors (MAX8511) ●Output Voltages: 1.5V, 1.8V, 2.5V, 2.6V, 2.7V, 2.8V,2.85V, 3V,3.3V,4.5V (MAX8510/MAX8511) and Adjustable (MAX8512) ●Low 40μA Ground Current ●Excellent Load/Line Transient●Overcurrent and Thermal Protection19-2732; Rev 5; 5/19Output Voltage Selector Guide appears at end of data sheet.Ordering Information continued at end of data sheet.*xy is the output voltage code (see Output Voltage Selector Guide).

The parts are available with preset output voltages ranging from 1.5V to 4.5V in 100mV increments. These devices can supply loads up to 120mA. As shown in the Functional Diagram , the MAX8510/MAX8511 consist of an innovative bandgap core and noise bypass circuit, error amplifier, P-channel pass transistor, and internal feedback voltage-divider. The MAX8512 allows for adjustable output with an external feedback network.The 1.225V bandgap reference is connected to the error amplifier’s inverting input. The error amplifier compares this reference with the feedback voltage and amplifies the difference. If the feedback voltage is lower than the refer-ence voltage, the pass-transistor gate is pulled low. This allows more current to pass to the output and increases the output voltage. If the feedback voltage is too high, the pass transistor gate is pulled high, allowing less cur-rent to pass to the output. The output voltage is fed back through an internal resistor voltage-divider connected to the OUT pin.An external bypass capacitor connected to BP (MAX8510) reduces noise at the output. Additional blocks include a current limiter, thermal sensor, and shutdown logic.Internal P-Channel Pass TransistorThe MAX8510/MAX8511/MAX8512 feature a 1Ω (typ) P-channel MOSFET pass transistor. This provides sev-eral advantages over similar designs using a PNP pass transistor, including longer battery life. The P-channel MOSFET requires no base drive, which considerably reduces quiescent current. PNP-based regulators waste considerable current in dropout when the pass transistor saturates. They also use high base-drive current under heavy loads. The MAX8510/MAX8511/MAX8512 do not suffer from these problems and consume only 40μA of quiescent current in light load and 220μA in dropout (see the Typical Operating Characteristics ).Output Voltage SelectionThe MAX8510/MAX8511 are supplied with factory-set output voltages from 1.5V to 4.5V, in 100mV increments (see Ordering Information ). The MAX8512 features a user-adjustable output through an external feedback net-work (see the Typical Operating Circuits ).To set the output of the MAX8512, use the following equa-tion:OUT REF V R1R2X -1V=where R2 is chosen to be less than 240kΩ and V REF = 1.225V. Use 1% or better resistors.PINNAMEFUNCTIONMAX8510MAX8511MAX8512SC70TDFN -EP SC70TDFN -EP SC70TDFN -EP 151515IN Unregulated Input Supply 232323GNDGround343434SHDN Shutdown.

Not intended as an electrical connection point.MAX8512Low-Dropout, 120mA Linear RegulatorsPin DescriptionShutdownThe MAX8510/MAX8511/MAX8512 feature a low-power shutdown mode that reduces quiescent current less than 1μA. Driving SHDN low disables the voltage reference, error amplifier, gate-drive circuitry, and pass transistor (see the Functional Diagram), and the device output enters a high-impedance state. Connect SHDN to IN for normal operation.Current LimitThe MAX8510/MAX8511/MAX8512 include a current lim-iter, which monitors and controls the pass transistor’s gate voltage, limiting the output current to 200mA. For design purposes, consider the current limit to be 130mA (min) to 300mA (max). The output can be shorted to ground for an indefinite amount of time without damaging the part. Thermal-Overload ProtectionThermal-overload protection limits total power dissipation in the MAX8510/MAX8511/MAX8512. When the junction temperature exceeds T J = +160°C, the thermal sensor signals the shutdown logic, turning off the pass transis-tor and allowing the IC to cool down. The thermal sensor turns the pass transistor on again after the IC’s junction temperature drops by 10°C, resulting in a pulsed output during continuous thermal-overload conditions.Thermal-overload protection is designed to protect the MAX8510/MAX8511/MAX8512 in the event of a fault con-dition. For continual operation, do not exceed the abso-lute maximum junction temperature rating of T J = +150°C. Operating Region and Power DissipationThe MAX8510/MAX8511/MAX8512 maximum power dis-sipation depends on the thermal resistance of the case and circuit board, the temperature difference between the die junction and ambient, and the rate of airflow. The power dissipation across the device is:P = I OUT (V IN - V OUT)The maximum power dissipation is:P MAX = (T J - T A) / (θJC + θCA)where T J - T A is the temperature difference between the MAX8510/MAX8511/MAX8512 die junction and the sur-rounding air, θJC is the thermal resistance of the package, and θCA is the thermal resistance through the PC board, copper traces, and other materials to the surrounding air. The GND pin of the MAX8510/MAX8511/MAX8512 per-forms the dual function of providing an electrical connec-tion to ground and channeling heat away. Connect the GND pin to ground using a large pad or ground plane.Noise ReductionFor the MAX8510, an external 0.01μF bypass capaci-tor between BP and OUT with innovative noise bypass scheme reduces output noises dramatically, exhibiting 11μV RMS of output voltage noise with C BP = 0.01μF and C OUT = 1μF. Startup time is minimized by a poweron cir-cuit that precharges the bypass capacitor. Applications InformationCapacitor Selectionand Regulator StabilityUse a 1μF capacitor on the MAX8510/MAX8511/MAX8512 input and a 1μF capacitor on the output. Larger input capacitor values and lower ESRs provide better noise rejection and line-transient response. Reduce output noise and improve load-transient response, stability, and power-supply rejection by using large output capacitors. Note that some ceramic dielectrics exhibit large capaci-tance and ESR variation with temperature. With dielec-trics such as Z5U and Y5V, it may be necessary to use a 2.2μF or larger output capacitor to ensure stability at temperatures below -10°C. With X7R or X5R dielectrics, 1μF is sufficient at all operating temperatures. A graph of the region of stable C OUT ESR vs. load current is shown in the Typical Operating Characteristics.Use a 0.01μF bypass capacitor at BP (MAX8510) for low-output voltage noise. The leakage current going into the BP pin should be less than 10nA. Increasing the capaci-tance slightly decreases the output noise. Values above 0.1μF and below 0.001μF are not recommended. Noise, PSRR, and Transient ResponseThe MAX8510/MAX8511/MAX8512 are designed to deliv-er ultra-low noise and high PSRR, as well as low dropout and low quiescent currents in battery-powered systems. The MAX8510 power-supply rejection is 78dB at 1kHz and 54dB at 100kHz. The MAX8511/MAX8512 PSRR is 72dB at 1kHz and 46dB at 100kHz (see the Power-Supply Rejection Ratio vs. Frequency graph in the Typical Operating Characteristics).When operating from sources other than batteries, improved supply-noise rejection and transient response can be achieved by increasing the values of the input and output bypass capacitors, and through passive filter-ing techniques. The Typical Operating Characteristics show the MAX8510/MAX8511/MAX8512 line- and load-transient responses.MAX8512Low-Dropout, 120mA Linear RegulatorsDropout VoltageA regulator’s minimum dropout voltage determines the lowest usable supply voltage. In battery-powered sys-tems, this determines the useful end-of-life battery volt-age. Because the MAX8510/MAX8511/MAX8512 use aP-channel MOSFET pass transistor, their dropout voltage is a function of drain-to-source on-resistance (RDS(ON)) multiplied by the load current (see the Typical Operating Characteristics ).MAX8512Low-Dropout, 120mA Linear RegulatorsFunctional Diagram*xy is the output voltage code (see Output Voltage Selector Guide).

双输出低压美线性稳压器ＭＡＸ8530
MAX8530是MAXIM公司生产的器件，它是一种双输出、低功耗、低压差线性稳压器。
该器件主要特点：输出1(OUT1)保证输出200mA；输出2(OUT2)保证输出150mA；OUT1及OUT2有多种电压输出(详见表1)，用户也可根据电路需要确定要求的OUT1及OUT2的电压(在1.5～3.3V范围之内)向工厂订货；两个电源是相互独立的并且都是低压差，在100mA输出时其压差典型值为100mV；工作电压范围2.5～6.5V；当OUT1输出电压低于87%正常输出电压时，RESET端输出100ms的复位信号(低电平有效)；静态电流小，典型值130μA；有省电关闭控制，关闭状态时耗电小于1μA；内部有输出电流限制，有过热及短路保护；有6焊球BGA及6管脚QFN两种封装；工作温度范围-40～+85℃。
管脚排列与功能
MAX8530的两种封装及管脚排列如图1所示，各管脚功能如表2所示。
QFN 封装用后缀EBT表示；UCSP封装用后缀ETT表示。
典型应用电路
MAX8530的典型应用电路如图2所示。
这是一个向基带μP供电的电路。
OUT1及OUT2的输出电压与型号的后缀有关，如表1所示。
输入电容器CIN取2.2μF，两个输出电容分别为2.2μF(OUT1)及1μF(OUT2)，这三个电容器都采用贴片式多层陶瓷电容器。
MAX8530的RESET直接与基带μP 的RESET接口。
当OUT1的电压降到正常电压87%以下时，MAX8530的RESET 输出低电平，使基带μP复位。
上拉电阻可取10～100kΩ。
该器件组成的稳压器适用于手机及无绳电话、PDA、数码相机、PCMCIA卡及无线局域网卡等。
